http://www.beamng.com/threads/rules-read-this-before-creating-a-thread-here.8/ First thing it says: Before suggesting something, make sure it hasn't already been suggested.

Christ if I do this search: https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=site:beamng.com stalling I get over 300 results. For something in such blatant disregard of how this section works, I don't do civility, nor was I particularly uncivil.
